Growth, fillet yield, and muscle quality traits are not affected by a genotype by diet interaction in rainbow trout consuming diets that differ in lipid content

چکیده

In this study, selectively bred rainbow trout (Oncorhynchus mykiss) with improved fillet yield were reared on three commercially available diets that varied in dietary lipid content: low (LL, 18%), moderate (ML, 24%), and high (HL, 29%–33%). The objective was to determine if a genotype by diet interaction affects product muscle quality traits (HY) (LY) lines of trout. Main effects the genetic line (p < 0.05) observed for viscera yield, carcass more favorable HY line. Analysis indicated selection did not compromise quality. A content at 2 kg harvest, which similar between LY LL HL diets, but greater ML diet. Collectively, these findings indicate higher yields will persist across variable crude lipid/energy contents.

Genotype-by-environment interaction of growth traits in rainbow trout (Oncorhynchus mykiss): a continental scale study.

Rainbow trout is a globally important fish species for aquaculture. However, fish for most farms worldwide are produced by only a few breeding companies. Selection based solely on fish performance recorded at a nucleus may lead to lower-than-expected genetic gains in other production environments when genotype-by-environment (G × E) interaction exists. The aim was to quantify the magnitude of G...

Genome-Wide Association Study for Identifying Loci that Affect Fillet Yield, Carcass, and Body Weight Traits in Rainbow Trout (Oncorhynchus mykiss)

Fillet yield (FY, %) is an economically-important trait in rainbow trout aquaculture that affects production efficiency. Despite that, FY has received little attention in breeding programs because it is difficult to measure on a large number of fish and cannot be directly measured on breeding candidates. The recent development of a high-density SNP array for rainbow trout has provided the neede...

Effects of dietary diludine supplementation on growth, proximate composition, muscle and texture structure of rainbow trout juveniles

A feeding trial which lasted for eight weeks was conducted to investigate the effects of diludine such as growth promoter on feed efficiency, muscle structure and proximate composition of juvenile rainbow trout. Diludine was added at 0.0(D0) 0.2(D1), 0.5(D2) and 1(D3) g kg-1 to a casein-based diet, and every diet was given to the triplicated groups of juvenile rainbow trout. At the end of exper...
